Self Consolidating Concrete - Overview of SCC - The Concrete ...

Let's start with the simple definition and then kick it up a notch. SCC is very exceptionally flowable concrete that never needs to be consolidated to fill forms or flow. Placed flat, like for a slab, it is virtually self-leveling. It looks a little like lumpy pancake batter. The consistency is measured by what's called slump flow, where we measure the width of the puddle left when a slump cone is filled and lifted. Slump flow for SCC varies from 19 to 30 inches. However, self-consolidating c...

Sep 29, 2011 · SCC is a highly flowable, nonsegregating concrete with a slump flow of 20 to 30 inches that can be easily placed and will fill forms completely under its own weight and without mechanical consolidation. SCC is produced using high-range water-reducing admixtures (HRWRA), viscosity-modifying admixtures (VMA), and well-graded aggregates.
